分享道德价值观是否会鼓励人们相互联系并形成社区？社会科学家已经认识到道德同质性（爱相同）的重要性，但驱动这种现象的道德相似性类型仍然未知。作者利用大规模的观察性社交媒体分析和行为实验室实验，调查了哪些类型的道德相似性会影响领带的形成。对超过 700,000 条推文的语料库的分析表明，社交网络中两个人之间的距离可以根据他们的消息的道德纯度内容（而不是其他道德内容）的差异来预测。作者通过在实验室中实验操纵感知的道德差异（研究 2）和相似性（研究 3）来重复这一发现，并证明纯度差异在社交距离中发挥着重要作用。这些结果表明，社交网络过程反映了道德选择，而线上和线下道德纯洁性问题的差异尤其能预测社会距离。本研究试图通过观察性大数据研究间接研究道德，并辅以使用传统社会心理学方法进行的两项验证性行为实验。
Does sharing moral values encourage people to connect and form communities? The importance of moral homophily (love of same) has been recognized by social scientists, but the types of moral similarities that drive this phenomenon are still unknown. Using both large-scale, observational social-media analyses and behavioral lab experiments, the authors investigated which types of moral similarities influence tie formations. Analysis of a corpus of over 700,000 tweets revealed that the distance between 2 people in a social-network can be predicted based on differences in the moral purity content-but not other moral content-of their messages. The authors replicated this finding by experimentally manipulating perceived moral difference (Study 2) and similarity (Study 3) in the lab and demonstrating that purity differences play a significant role in social distancing. These results indicate that social network processes reflect moral selection, and both online and offline differences in moral purity concerns are particularly predictive of social distance. This research is an attempt to study morality indirectly using an observational big-data study complemented with 2 confirmatory behavioral experiments carried out using traditional social-psychology methodology.
